by any chance are doing the junior cert. ? :L
you need to use two acids ( dilute hydrochoric acid and sulfuric acid) and one base (sodium hydroxide solution) +litmus indicator.

What is the method used to carry out an investigation to study the pH changes that take place when neutralisation reactions occur between two named acids and a named base?
Titration
What pH changes occur when Neutralisation reactions occur between two named acids and a named base?
Um I have a strange feeling your doing the junior cert :L
Chemical reactions always involve changes in a chemical?
There will always be changes in one of the reactants. In some chemical reactions, one of the chemicals works as a catalyst to encourage a reaction between two or more chemicals but does not change during the reaction.
Why methyl orange used as indicator in titration instead phenolphtalein?
The choice of which indicator to use is determined by the range of pH where the indicatir changes colour and the equivalence point of the neutralisation reaction. Methyl orange changes color between pH3 and 4, phenolphthaein between and 8 and 10. It depends on what you are titrating which one you choose.
Is the reaction between aluminum and copper chloride a physical or chemical change?
All chemical reactions are chemical changes.

What do you find out about the pH changes that take place when neutralisation occurs between a strong acid and a strong base?
pH7,Which It Water.
Changes color at the endpoint of titration?
indicates end of titration neutralisation of the reaction
What substance changes during reactions between hydrogen peroxide and liver?
The substance that changes is the hydrogen peroxide. After it reacts, it forms bubbles of oxygen and water.

What is the enthalpy change of neutralisation for strong acid with a strong base?
The enthalpy of neutralization of a strong acid against a strong base is always constant (13.7 kcal or 57 kJ mole-1). It is because in dilute solutions all strong acids and bases ionize completely and thus the heat of neutralization in such cases is actually the heat of formation of water from H+ and OH- ions, i.e., H+ + OH- ---> H2O; ΔH = -13.7 kcal
Is oxidation nuclear?
No, its chemical.nuclear reactions involve changes in only the configuration of the nucleuschemical reactions involve changes in only the configuration of valence electrons
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
